按标签搜索 FlickR 照片
Search FlickR Photos by Tag
我正在尝试查询 FlickR 照片并收到 JSON 响应。我正在使用 Retrofit 调用 FlickR API。在我的代码中,用户输入文本,这是通过 EditText 捕获的。我想根据这个词查询。我从 Flick 收到以下错误:"Parameterless searches have been disabled. Please use flickr.photos.getRecent instead."
public class MainActivity extends AppCompatActivity {
private EditText mSearchTerm;
private Button mRequestButton;
private String mQuery;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSearchTerm = (EditText) findViewById(R.id.ediText_search_term);
mRequestButton = (Button) findViewById(R.id.request_button);
mRequestButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mQuery = mSearchTerm.getText().toString();
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://api.flickr.com/services/rest/")
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.build();
ApiInterface apiInterface = retrofit.create(ApiInterface.class);
Call<List<Photo>> call = apiInterface.getPhotos(mQuery);
call.enqueue(new Callback<List<Photo>>() {
@Override
public void onResponse(Call<List<Photo>> call, Response<List<Photo>> response) {
}
@Override
public void onFailure(Call<List<Photo>> call, Throwable t) {
}
});
}
});
}
//Synchronous vs. Asynchronous
public interface ApiInterface {
@GET("?&method=flickr.photos.search&api_key=1c448390199c03a6f2d436c40defd90e&format=json") //
Call<List<Photo>> getPhotos(@Query("q") String photoSearchTerm);
}
}
根据他们的 API docs,您希望将 text
作为 @Query
参数而不是 q
传递。所以喜欢:
Call<List<Photo>> getPhotos(@Query("text") String photoSearchTerm);
其他:
• 可能想对 post 隐藏 API 密钥。
• 可能需要用if(!TextUtils.isEmpty(mQuery))
将代码包装在onClick()
方法中,以防止问题再次发生。 (也可以将 TextChangeWatcher 添加到您的 EditText 和 enable/disable 基于 EditText
中字符串长度的搜索按钮
